Breach of contract, lies and bad service

I purchased a grafton Everest lounge set on the 8 Dec 2017. The lounge set was meant to arrive one week later and guess what it did not. I was been kept on telling lies from the branch and the wharehouse.

I had to call multiple times to the store to get answers.

When I spoke to them they said it was raining so they cannot deliver, so I called the whatehouse and asked if it was raining they said no... and they will deliver the next day... number 1.

The next day came and they said they cannot deliver due tho the set they have for me is damaged and the will deliver the next day when new stock arrives... lie number 2.

Finally the day of arrival of the stock... when we opened the box only to realize the set is damaged, hence it was no t raining, there was no new stock arriving at the wharehouse cause they sent the same damaged set.

Breach of contract...

I have also purchased a bed with the lounge set and by paying cash, I will receive a cash back of 500 rand multip**** by 2 because two items was purchased. I have canceled the sale of the lounge set but now the tell me I can’t get the cash back of 500.
